Finite-Difference Time Domain Techniques Applied to Electromagnetic Wave Interactions with Inhomogeneous Plasma Structures

Figure 14

Magnitude of the electric field, in volts/meter, within the inhomogeneous plasma cylinder obtained by the FDTD simulation for different incident frequencies f_in. Central electron density is set to n₀ = 5 × 10¹⁷ m⁻³, and electron collision frequency is set to ν = 500 × 10⁶ Hz.

(a) f_in = 5 GHz

(b) f_in = 10 GHz

(c) f_in = 15 GHz
